Hi,
I want to calculate throughput rate using data that nRF52840 dongle working as sniffer captured.
Wireshark shows 'time' , 'delta time' and 'packet time'.
I think 'time' is incorrect.
For example, about IFS, 'delta time' shows 150 us but 'time' shows more than 1 ms.
・What dose 'time' means ?
・Do ’delta time’ and 'packet time' show correct time ?
Best regards
Hi
Your assumption that time is incorrect in regards of data transmission is correct. This parameter is at what time each packet is received over the COM port to Wireshark, and has nothing to do with the on-air transmission per se.
Delta time should indeed show the correct time that each radio event takes to complete, so that should show you the correct time between each advertising packet. As for the "Packet time" you are seeing, I don't have this parameter on my Wireshark, can you show me what "Field" this is in the Wireshark "Column preferences"? You can get to the menu pictured below by right-clicking any of the columns in Wireshark and press "Column preferences" in the dropdown menu.
Best regards,
Simon
Thank you for your reply.

If nRF52840 dongle working as sniffer receives large data many times in a row how dose it works ?
May sniffer fails to receive some data because on-air transmission is faster than transmission over COM port ?
"Packet time" is here(see attached picture)
